The problem of dew condensation inside a sauna room is prevented and air inside the sauna room is enabled to circulate in a power-saving mode with a sauna system including a sauna room having a space that a user can enter/exit; a steam supply pipe for supplying steam into the sauna room; and a fluid circulation generation device disposed at a predetermined position inside the sauna room. The fluid circulation generation device circulates steam inside the sauna room in the vertical direction.
